-exact description o the invention, such as` will enable others skilled in the art to which it ppertainsto make and use the same.

y invention. relates to Scrapers, and particularly to that'k type which has means for raising and lowering their scoo sections and for transporting the scraped irt for a considerable distance.-

The object of the invention is the provision of a device ofl this character by which the dirt may besc'ooped in the body of the device and the bod raised so that the ldirt Amay. be transporte for a considerable disment-of parts, as will be more fullydescribed wand particularly pointed out in the appended` claims. v.

In the accompanying drawings, Figure `1 is a side elevation withone of the supporting wheels removed,l Fig. '2 is a top plan view, Fig. 3 isa vertical section on the llne 3 3 of Fig. 2, Fig. 4:-is a vertical section lon the line 4-4 of-Flg. 2, Fig. 5 isa-detail vertical sec-` tion on the line5`5 of Fig.`l` 2, and Fig. 6 is a vertical section showing the scoop sections in dumping position.-

Referring more especially to the drawings, 1 represents an axle which has the oH-set stub ends 2, upon which the supporting wheels 3 are mounted. Secured to this `axle is a frame which com rises side plates 4, to which are connected the side plates 5, havin squared apertures 6, to engage the oli-setv en 2 of the axle. The side plates 4 have connected to? their forward ends the U-Sha ed front plate 6 and the draftv members 7 Y an 8, the former extending diagonally forward, and the latter extending directly forward to `Specification of Letters Patent. Application 'lled .Tune 16, 1908. Serial No. 438,617.

1 the door 25 is raised through t Patented oct. c, 190s.

be enga ed with the ole 9. The side plates 4 extenv rearwardly ack of the axlewhere they are apertured at 10, to-receive the shaft 11, u ony which is journaledy the side plates 12, o the scoop sections. These scoop sec- 4 tions which are numbered 13 and 14 are pivplate as at 15 and16, and the .oted to vthe latter comprlses an L-shaped troughl with ilanged sides through which the pivotal bolts 17 pass.` The former scoop section 13 comprises a flat sheet of metal having flanged sides 18, through which the pivot bolts 18a,

which secure the flange section 13 to the side plates 12 plass, also through vertical lever arms 19, W 'ch are connected by the rod 20. livoted to the rod 20 is a locking arm 21, having at its rear end a right angular bend V22, and a foot piece 23, which is adapted to engage the upper edge 24, of the scoop section 14, so as to hold the sections in alinement when in position to he used as a cart, or as a scoop.l Y In order to hold the dirt within the device when transporting it for long distances I hinge to the frame member 6 a door 25, which has pivotedto its front face a locking lever 26, having at itsI o posite end a notch 27, adapted to vengage t e s uared head of the bolt 28, passing through t e lug 29, upon the ole 9. Pivoted intermediate the length of t e locking lever 26, is a release lever 30, which has its other end pivotall connected to the lug 29. The pivotal bo t which secures the release lever to the locking lever also holds a manipulating handle 31, which extends'back adjacent the operators seat 32. When this lever is pulled in a rearward direction'and depressed, fulcrumed upon the axle e operating lever 26.4 When the door is closed and the notchin engagement with the lug 29 the weight of. the dirt upon' the door will only tend to holdvit more securely in place. In closing thefront door, the lever or manipulating handle31 is moved forward'and in a slight upward direction which forces the link 30downwardly, thus .acting with the rear endof the locking lever 26 to form a toggle lever which forces the door to closed osition.

Extending vertically from the si e members 4 are a pair of pedestals 33, in which is journaled the winding drum 34, having flexible connections 35, with the side members 12, so as to raise and lower them when necessary; In order to adjust the height of the scoop sections I provide a pair of ratchet wheels 36 and 37, the former of which is adapted to prevent the drum from unwinding, and the latter of which is adapted to wind the drum when operated', as will now be described. The ratchet 36 is journaled between two plates 38, which have pivoted therebetween a pawl 39, which is adapted to engage the ratchet and be held in position by a spring 40. The latter wheel 37 is secured between the side plates 41 of the lever 42, and is operated by the awl 43, controlled as is usual by the h and ever 44, and held in normal position by the spring 45. The uper end of the hand lever is provided with a ibop 46, by which the pawl may be held disengaged. Upon the orward movement of the lever 42, the pawl rides idly over the ratchet wheel 37, and upon the backward movement thereof engages the ratchet and turns the drum so as to wind u the flexible `connections and thereby raise t e scoop sections. When it is desired to release the drum so as to lower the 'shafts the loop 46 is engaged with the handle of the lever so as to release the pawl from the ratchet and thel foot ,piece 47 of the pawl 39 is depressed allowing the drum to unwind and the scoop to dro tothe scooping position. After sufficient 'rt has been scooped upon the sections 13 and. 14 the may be raised by operating the lever, as efore described, the door 25 being referably o en at the time and subseuentllyr closed. hen it is desired to dump t e device thefdoor 25 is o ened by drawing backward and depressing the lever 31 and releasing the locking arm 21, which Jrees the sections and allows them to drop by the weight of the dirt in the scoops. In order to limit the inward movement of the scoops I provide V-shaped lugs 48, connected to the sides 12 so as to be in the path of the scoop when raised.

Riveted to the outside of the lates 38 and extending rearwardly there rom are two parallel seatsupporting members 50, upon which the seat 32 is supported. The right hand one of these seat supporting members is extended forwardly and is provided with v a right angular extension 51, which actsas a stop for the lever 42. The

lrear' end of the seat supporting member 50 is provided with a brace rod 52, which extends down from underneath the seatto the shaft 11, and thereby braces the members 50. From the foregloing description, taken in connection with t e accompanying drawings,

4members carried by said frame, means to raise and lower the scoop frame, and means to lock the scoop sections in operative position.

` 2. The combination with a wheeled support, of a scoop frame pivoted thereto, means for raising and lowering said scoop frame, a pair of scoop sections ivotally mounted upon the frame, means to ook said scoop sections in operative position, and means hinged to the front of the support for closing the front of the frame.

3. The combination with a wheeled support, of a scoop frame pivoted to said support, a pair of scoop sections pivotal y mounted upon said frame, means for holding the scoop sections in operative position with their bottoms alined, means for raising and lowering the scoop frame and its associated sections, means for closing the front of said ,scooplrame, and means for operating said closing means.

4. The combination with a wheeled support, of a scoop frame pivotally secured thereto, a pair of dumping scoop sections pivotally mounted upon the scoop frame and having their inner edges meeting in the center of the frame, means for limiting their inward movement, means for locking them in normal scooping osition, means to raise the scoo frame an associated sections to normal orizontal position, means to close the front of the scoop frame, means to operate said controlling means, and a self operated lock carried by said o erating means.

In testimony whereof I ave hereunto set my hand in presence of two subscribing witnesses. l
